In the middle of performing "Mr. Ambiguous," Hwasa's romper straps, stretched to breaking point when she thrusts her arm out, falls out of place. Af first, Hwa Sa doesn't seem to notice her loose straps, but soon catches on and awkwardly holds them in place with her hands while continuing to sing and dance. She subtly sends a signal for help with her eyes at the other members, and Whee In, during a part of the choreography in which she stands right behind Hwa Sa, manages to deftly fit the straps back in place. 

That's some real skill right there. Check out the seamless teamwork that saved Hwa Sa from accidentally baring all to the world in the clip above!
